LANSING ONDERDONK, OF PLAINFIELD, NEW JERSEY, ASSIGNOR OF ONE- HALF TOHENRY P. WELLS AND CAMPBELL 0. BROWN.

RUFFLIN G AND PLAITING' ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part-t Letters Patent No. 272,309, dated February13, 1883.

Application filed August 25, 1881. (Model) To all whom t't may concern:

Be it known that I, LANSING ONDERDONK. of the city of Plainlield, in thecounty of Essex and State of New Jersey, have invented a new and usefulImprovement in Bnffling and Plaiting Attachments for Sewing- Machines,of which the following is a specification, reference being bad to theaccompanying drawings.

This invention relates to certain improvel0 ments in and upon a plaitingattachment for sewing-machines for which Letters Patent ot' the UnitedStates numbered 231,844. were granted to me and to Campbell 0. Brown andHenry P. Wells, August 31, 1880.

The improvement consists in the construction and arrangement of parts,as will be hereinafter described in the specification and pointed outinthe claims.

Figure 1 illustrates a perspective view of my attachment as improved,looking on the left side of the same, and showing said frictionclutchand the parts co-operating therewith.

Fig. 2 represents the bed-piece which sustains and upon which travel theworking parts of 2 my invention, as modified, viewed from the rightside. Fig. 3 represents the switch-lever,

its follower, and its spring, which form part of the shifting device.Fig.- 4 represents the same, showing the switch-lever thrown to one sidein the position it assumes in the act of throwing over the tumblerattached to the upper slide to lock the same to one of thecloth-carrying slides. Fig.5representsa portion of the bed-piece, viewedfrom underneath,

5 to show the recess, in which are placed the spring and the follower,through which its mo tion is transmitted to the switch-lever. Fig. 6shows a perspective and elevation of the said follower. Figs. 7 and 8show a lockinglever 4.0 in combination with the switch-leveraforesaid,by which the motion of the latter is controlled, so that thecarrying-slide may be made to engage continuously with eithercloth-carrying slide at will. Fig. 9 shows a portion of that 4 5extremity of one of the cloth-carryin g slides to which thecrimping-blade is attached, and a hook hinged to the same. Fig. 10 showsthe same with the hookremoved, and shows a recess and thespiral springtherein for the purpose of erecting the hinged hook when the same ispushed aside. Fig. 11 represents another view of a portion of thebed-piece, when viewed from underneath, as combined with-thelocking-lever, the switch-lever, and a portion of one of thecloth-carrying slides. Fig. 12 shows a detached view of an auxiliarylever adjustably connected to the operatinglever, and which actuates thecarrier to which the friction-clutch is attached. Fig. 13 shows adetached view of the carrier to which the friction-clutch is attached.Fig. 14. represents the friction-clutch. Fig. 15 is a detached view of aspring which, when the parts are assembled, is fastened to the carriershown in Fig. 13, and bears upon one or-the other of the inclinedsurfaces of'the friction-clutch. Fig. 16

is a detached view of the switchlever. Fig.

18 shows a plan and perspective view of the locking-lever. Fig. 19 showsa latch which is hinged upon the upper surface of the carryin'g-slide,and which serves to lock the same to the carriershown in Fig. 13 when itis desired to gather. Fig. 20 shows the extremity and surface of thecarrying-slide upon which the latch aforesaid is fulcrumed.

Like parts of this and my former patent are indicated by like letters. g

In the drawings, A, as in my former patent, indicates a plate adapted tobe secured to the bed of a sewing-machine, to which is attached So thecasing A,in which the carrying and clothcarrying slides move back andforth.

B indicates a carrying-slide simiiarin all respects to the rack-bar inmy former patent, except that the teeth forming the rack are omitted.

Band B represent the cloth-carrying slides, as in my former patent.

U is the friction-spring, as heretofore.

E is the vertical standard, to which, at its upperend, is fulcrumed thelevers F and I, as

' before. These levers are placed on the left instead of the right sideof the standard. The form of the standard isalso changed, as shownclearly in Fig. 2. p v

I is the supplemental lever, fulcrumed to the standard E, and connectedwith the operatinglever F, as before, except that it is attached to theleft side of the standard, as aforesaid. This supplemental lever is ofthe form shown inthe detacl l'ed view, Fig. 12. Its lower extremityterminates in a fork, i, which engages with a stud, G, pr jecting lromthe reciprocating carrier H, which is connected with the bed-piece bytwo screws, h h, pas ing through the slots 99, so that the carrier H maymove to and fro through a distance equal to the length of the slots. Thesaid carrier H carries with it, and

' fuleru med to it by a screw, h passing through an oval slot. h, Fig.13. a friction-clutch, J, provided with two pins,jj, between which thecarrying-slide B pnSRGS. A spring, K, is attached to the carrier H, itstree end bearing on one or the other of the inclined surfaces of thefriction-clutch J. This friction-clutch is the same invention for whichLetters Patent ofthe United States, dated August 31, 1880, and on mbered231,843, were granted to me, Campbell 0. Brown, and Henry P. Wells. foran automatic reversible clutch. and its form and method of operation arethe same as shown and described in that patent, except that in thepresent application the said clutch is inverted.

M indicates an adjustable trip, as in my formerpatent,except that thesameis straight and not curved. A short pin fastened in and projectingabove the upper surtace of the carrying-slide B serves to trip theclutch J when the slide B is moving inward, and it is substituted forthe curved trip L in my former patent. It is not shown in the drawings;but it is placed just over the forward end of the safety-notch shown anddescribed in my Letters Patent for the clutch aforesaid, so that it willcome in contact with the upper pin,j, of the friction-clutch when thecarrying-slide B has moved inward almost to its shoulders, and thus tripand reverse the clutch. In Fig. 1 of the drawings of the presentapplication (with the carrying-slide Bin the position shown) this pin isconcealed by the stud G on the carrier H. The carrying-slide B isprovided at its bent extremity, on its lower side, with a tumbler orshifting device, as before.

The forward end of the bed-plate A is channeled out, as shown at O inFig. 5. In it (see Figs. 3 and 4) is placed a spring, T, one end ofwhich bears against the side of the recess and the other against anL-shaped follower, a. (Shown detached in Fig.6.) The switch-leverV(shown detached in Fig. 16) is fulcrumed at t; on a pin inserted in thebed-piece, and vibrates from side to side on the same, in the plane ofthe bed-piece. A locking-lever, P, is attached to the lower side of thebed-piece by a serew,p, on which it is fulcrnmed, as shown in Fig. 11.(See also Fig. 2.) It is enlarged at its shorter extremity, where it isprovided with an opening, 1)", which embraces a pin, 4, inserted in theswitchlever V, so that the motion of said switch-lever V may becontrolled thereby. The bed'piece. A is provided with a recess, as shownat 0, Fig. 2, so as to form a stop for and restrict the motion of thelockingleverP by encountering the pin 0 when the locking-lever is movedin either direction to its proper limit. The form and method ofcombination ofthese parts-to wit, the switch-lever V and thelocking-lever P-will be clearly seen from, inspection of Figs. 3 and 4,which show them in operative position when viewed from below, and Figs.7 and 8, which show them viewed from above.

A latch, L, (shown detached in Fig. 19.) is secured to the upper surfaceof the carryingslide 13, as shown in Fig. l, and is so arranged thatitsextrcmity L, when the slides are in the position shown, may be lockedinto the slot L in the carrier H.

The forward extremity of the lower clothcarrying slide, 13 is providedwith a book, as heretofore, but of the form as shown in Fig. 7, whichshows the same viewed from under-- neath.

The upper cloth-carrying slide, B, terminates as shown in Fig. 10. It iscountersunk at a to receive a spiral spring, one end of which spring issecured to the slide, and the other end to a hinged hook, Q, secured tothe lower surface of said slide, as shown in Figs. 8 and 9. The hingedhook Q is pivoted to the lower surface of the slide B at a, Fig. 9. Astop and pin, (1 prevent its moving too far in one direction, while theextremity marked .70 is bent upward so as to strike against theprojecting end of the slide, (markedy, Fig. 10,) and thus limit itsmotion in the other direction.

Having now described the various parts of my invention, so far as thesame have been varied from my former patent, 1 will now describe themethod of their operation.

The lever F, being attached to the needlebar of the sewing-machine,rises and falls with it, and imparts its motion to the supplementarylever I, as before. As the lever I oscilhates it carries the stud G withit, and thus imparts a reciprocating motion backward and forward to thecarrier H. To the carrier H is i'ulcrumed at h the friction-clutch J.The folcrum-screw of said clutch is fastened in the clutch, passingthrough an elongated opening in the carrier H, as shown at Ir, Fig. 13,so that the clutch may rise and fall slightly as its inclination varies.Thecarrying-slide 5 passes between the pins jj of the clutch. Theinterval between said pins-is sufiicient to allow the slide to passfreely when the clutch is nearly perpendicular; but when the clutch isinclined to any extent it is clear the pins will grip the slide firmly,and it the clutch moves the slide must move with it. The position of thespring K, asit bears upon the one orthe other side or the double inclineforming the upper edge of the clutch, determines the direction in whichthe slide B will be moved. When the apex of the clutch inclines towardstop M the spring K will bear upon the incline nearer the latch L. (SeeFig. 1;) Then,as thcleverFrises and B will be movedinward.

the carrier H is moved toward the stop M, the pins of the clutch willslip over the carrying slide B; but when the motion is reversed and thecarrier H moves inhe opposite direction the spring tends to and doesincline the clutch and jam the slide between its pins, and the more theslide resists the more the clutch tends to incline and the tighter itbites the slide. Thus as the carrier H continues to move it drags theclutch, and consequently the slide,

with it until the motion of the carrier H is reversed. Then the clutchslips back and with the next change of direction of the carrier H takesa fresh hold and moves the slide, as before. Thus the slide B is movedforward intermittently in one direction as long as the spring K bears onthe incline of the clutch aforesaid; but should the bearing of thespring be shifted to the other faceit isclear that-the clutch will thenslip on the downstroke ofthe lever F and bite on the upstroke, and theslide The position of the spring K. and consequently of the clutch, andthe direction in which the slide B will move, will all change wheneverthe pins of the clutch come in contact with anything which arrests themotion of the clutch, while the carrier H continues to move. Theadjustable stop M furnishesonesuchobstacle,andapi'nsetinthecaerying-slide B in a position nearly abreast the stud G (when the slideBisin the position shown in Fig. l) furnishes the other. Thus thecarrying-slide B receives a reciprocating motion of greater or lessextent, governed by the position at which the adjustable stop M isplaced. The motion of the slide B is transmitted to the cloth-carryingslides B and B as follows: The slide B is provided on its under sidewith a shitting-device or tumbler, just as in my former patent, No.231,844. As the slide B moves outward the pin on the under side of thistumbler engages in the book of one of'the cloth-carrying slides, B or B,as heretofore and carries the slide with it. The slide B, having movedits allotted space, reverses and begins to go back. The pin on thotumbler (marked B, Fig. 7) then encounters theincline zjust below thehook,'and is drawn down said incline to the bottom thereof, as shown inFig. 7. This moves the tumbler over and disengages the pin R from thehook. Both slides (let us say B and B go inward together until positionof the said switchlever is upright, as

- line of the slide.

shown in Fig. 3. The incline .2 at the bottom of the slot in the slide Bis so constructed that when the pin R of the tumbler reachesiis bottomit (the pin) will lie outside of the median Since the apex oftheswitchlever Vis on thisline, the pin Rot the tumbler is caught betweenits point and the inclined portion of the hook 3 in the end of the slideB. Any tendency to jam is relieved by tho this continues until the pin Rhas passed the hook of the slide B. Then, since it is free to move inthat direction, the switch-lever V:

throws it over into engagement with the hook of the slide B. and on thenext trip of the carrying-slide B the cloth-carrying slide B goes withit, while B remains at rest. Box-plaitiing is the result.

It is clear that the switch-lever V cout'ifol's f in great measure thealternate engagement of the pin B with the hooks of the slidesB and BIt, therefore, the switch-lever be locked while inclined ineitherdirection and retained in that position, the pin R of the tumblerwill not be thrown over, and will consequently remain constantly engagedwith one and the same slide. This is the office of the locking device P.(See Figs. 7 and 8.) It the same is set at the 3 stamped on thebed-piece, (see Fig. 2,) the switch-lever will then be locked, as shownin Fig. 8, and only the slide B will act on the'cloth, and knife or sideplaiting will result. If, on the contrary, itis set at the "2 stamped onthe bed-piece, (see Fig. 2,) then the lower slide, B alone will beconstantly carried out and in, and knife plaiting, but with the fold theother way, will result. If set at 1, as stamped on the bed-piece, theswitchlever is free, and the attachment is ready to do box-plaiting.

Should it be desired to gather, when the slides areal] in the positionshown in Fig. 1,

place the projection L of the latch Linto the slot L of the carrier H.The carrying-slide will then be moved directly by the carrier H 'throughthe latch L, and will move backward ate my invention as improved.

Having now described my invention, what I claim as new, and desire toPatent, is--- l. The combinatiomwith the actuating-levers, one of whichis adapted to be attached to the needle-bar of a sewing-machine and toengage with the other, of a reciprocating carrier, a friction -clutcnhaving reversely inclined bearing-surfaces, and the spring K, adapted tobear against either inclined face of said clutch for the purpose ofholding the clutch in position to operate in either direction.

2. In a. gathering and plaiting attachment, the combination of acarrying-slide, B, a friction-clutch, J, mechanism for operating saidIIO clutch, the carrier H, and devices connected to and moving with saidcanning-slide for tripping said clutch, whereby the said clutch will beprevented from feeding the carryingslide beyond a certain point in onedirection, and upon being reversed will move the same in an oppositedirection, substantially as spec-i fiedl.

3. The combination of the cnrrying'slide provided with the latch L, andcarrier H, pro vided with asuitnble recess, the operatinglevers, and theclutch J, whereby the said can ,rier may be looked to saidcarrying-slide for the purpose of gathering, substantiallyas describedand shown.

4. The combination, with the carrying-slide and mechanism forreciprocating said carrying-slide, the clothmarrying, slides providedwith engaging books, a tumbler pivoted to the carrying-slide, providedwith a pin, R, the switch-lever V' and its follower u, and spring T,whereby the tumbler is shifted, so that its pin B maybealternatelyengaged by thehooks of the respective Slides, substantiallyas and for the purpose specified.

In testimony that I claim the foregoing improvement in plaitingattachments for sewing- .mnchines, as above described, I have hereuntoset my hand this 22d day of August, 1881.
